Application tiled4 Kay L9,

My invention relates to soot blowers especially designed for use in connection with liretube boilers in which the tube groups are separated by vertical spaces. The ob- 5 ject oil my invention is to provide a soot blower of simple andeiiicient construction whereby the different tube groups or sections ot the tube groups can be separately blown teclear out the soot and whereby` the soot l blowing devices canzbe swung. away from the tubes in sections when, for any reason, it is desirable to get at the tubes.

The nature of my improvements willbe best understood asdescribed in connection l with the drawings infwhich they are illustrated and in which i. i A Figure -1 is a front elevation of a fire tube boiler providedwith my.A improvedsoot blowing apparatus. 1 l

A indicates the boiler which, as shown in Fig. 1, has three separate tube groups, the first consisting of three vertical rows of tubes indicated at B. B', B2. The second or centra] group is made of seven vertical rows of tubes, indicated at C, C', C2, C", C", C5 and C", while the third group of tubes is made up of three vert-ical rows indicated at D, D', D2. The vertical spaces indicated between the tube groups are indicated at b, c. E indicates a steam conduit having branches indicated at E and e. 1 The branch E connects with two conduits indicated at E2 and F. The conduit E2 is continued, as indicated, at EE", E4 and E*i and terminates in an upwardly extending vertical portion E in which is rotatably secured the steam conduit indicated at I. The upper end of this conduit, see Fig. 4, is closed by a plug-I was.` serial. No. 640,139.

above which is `formed a tubular seat Il. I? isa steam pipe extending out horizontally from the rotatable steam` Conduit I to the inner face of which, and pneferably, as shown, so as toextend inward `from the conduit Ir, are securedftheA serieseof Steam conduits I* arranged so astoregistenwith the vertical tube rowsB, Bf. B2, and from which entendi steam nozzles J located so asto register with thendividimltubesoftheserows. Thepipe es system described constitutes assent blower` frame. and` auch a trame mancbviously be made` up @i different arrangements of conf; nected pipes.. .i

` The branch F- extending fromqthe steam pipeE' `iS continued, as indicated, at F', F2; and F3 and connects with the `vertical con duit K which lies in between `the rotatable pipe I- and. the head of.; the boiler` anditerminates `in aretnrnhend K in` which iarota` 75 tably secured the conduit L` which is alsa rotatably supported on thefthimblc `LF secured in the socket I2 ofthe conduit I and provided with a block indicated at L". From the rotatable conduit L extends the horizontal conduit L3 to which is secured a series of vertical conduits L, L4, arranged to register with certain tube rows of the. intermediate bank of tubes and provided with nozzles J which register with the individual tubes.

At the right hand side of the construction shown in Fig. 1 I have shown a conduit e' leading from the pipe E and connecting with branches f and e2 shaped and continued like the conduits shown at E2 and F and connecting with similar rotatable conduits I and L. At G and G I have indicated valves at the 'unction of the branches by which steam can e turned into the conduit I or conduit L at will or shut ofi' from both of them. At M I have indicated a bracket for properly spacing and supporting the rotatable conduit I and the conduit K, and at M I have shown a bracket secured to the reverse coupling K at the head of the pipes K.

O, O, etc. indicate brackets extending out from the soot blower pipes, grooved to receive a rod P which, when' in place, holds the different independently movable parts of the soot blowing apparatus in position.

The operation of my device is, of course, obvious. Steam can beturned into any of the different separate parts of the soot blowing system at will and when it is desired to In the construction shown in Fig. 8, my

device is adapted for a boiler having two tube groups separated by a wide space so that two sets of rotatable vertical aligned conduits. indicated at z' and l, can be used.

Independent steam pipes E, E6 and F, F3,

are here shown as supplying the upper and lower conduits. The horizontal conduits are indicated at Z3 and the vertical conduits at Z. In Fig. 9, al modification is shown in which my device is adapted for use with a boiler having four separate groups of tubes.

Having now described by invention, what I claim as new and desire to secure by Letters Patent, is:

l. In combination with a tire tube boiler having tube groups separated by vertical spaces, a soot blower construction comprising rotatable steam conduits arranged opposite to the vertical spaces between the tube groups, tubular soot blower frames connected to each rotatable conduit and steam nozzles connected to said frames spaced to register with the tubes of the respective tube groups when in operative position.

2. In combination with a fire tube boiler having tube groups separated by vertical spaces, a sot blower construction comprising pairs of independently rotatable verticallyv alined steam pipes opposite to the vertical spaces between the tube groups, tubular soot blower frames `connected to each rotatable pipe having nozzles arranged t0 register with the tubes of the respective groups of tubes when the frames are in operative positions and means whereby'steam can be admitted at will to any one of the vertical rotatable pipes.`

3. In combination with a fire tube boiler having tube groups separated by vertical Spaces, a soot blower construction comprisingpairs of independently rotatable vertically aligned steam pipes o posite to the vertical spaces between the tu e groups, tubular l soot blower frames connected to the respective rotatable pipes and stem nozzles secured in the tubular frames to register with the tubes, vertical steam supply pipesv connected to the upper rotatablefpipes` and ex-J tending down between the rotatable pipes and the boiler head, a steam supply pipe connected to the bot-tom of each lower rotatable pipe, means connecting the respective .supply pipes of each pair of rotatable pipes, a main supply pipe connected to said means, and a valve in each of said means arranged to permit steam to be admitted to either ot' 1 the respective supply at will.
